Objective The aim of this study was to investigate the distribution of body weight related index and to explore the relationship between weight related index and cardiovascular diseases in rural residents in Yunnan Province. Methods By random cluster sampling method,rural residents were selected in Yunnan Province. The data were collected by face-to-face questionnaire and medical examination. Results 4070 rural residents in Yunnan participated in this study. The survey results showed that gender,age,education level and ethnicity affected both the distribution of body weight related index and low body weight,overweight,obesity,and central obesity(P < 0.05). Compared with low body weight,non overweight,non obesity and non central obesity group,non low body weight,overweight,obesity and central obesity group had higher prevalence rate of hypertension(P < 0.01). Among central obesity group,the prevalence rate of coronary heart disease was higher than non central obesity group(P < 0.01). Conclusion The distribution of body weight related index in rural residents of Yunnan province showed some special characteristic. The overweight,obesity,and central obesity were related to cardiovascular diseases. Change unhealthy living habits or behavior as well as improving their cultural quality have effects on controlling body weight related index and help to reduce the prevalence rates of overweight,obesity and central obesity which can further reduce the prevalence rates of cardiovascular diseases.

Objective To measure the burden of chronic obstructive pulmonary disease (COPD) in a rural area of Kunming. Methods Shilin County was selected as the study region. Disability adjusted life years (DALY) was used to measure the burden to COPD. Results The overall prevalence of COPD was 6.68% , and males had higher prevalence of COPD than females. Females accounted for higher YLL rate and DALY rate due to COPD than males, whereas males had higher YLD rate due to COPD than females. People aged 60 years and over were responsible for higher YLL rate, YLD rate and DALY rate due to COPD compared to other age group. Conclusion COPD does harm to males' quality of life whereas threatens females' death in the study region. The region should focus on further prevention and control of COPD.

Glucagon-like peptide-1 (GLP-1), one kind of incretins, contributes to control blood glucose level with several routines. It can be degraded rapidly by the enzyme dipeptidyl peptidase IV (DPP-IV). DPP-IV inhibitors augment glucose homeostasis by preventing degradation of GLP-1, which can stimulate insulin secretion, inhibit glucagon secretion, increase satiety, and slow gastric emptying. They are weight neutral, and are associated with low risk of hypoglycemia. This review highlights the characteristics of GLP-1, clinical efficacy, pharmacokinetics and adverse reactions of DPP-IV inhibitors.

An electrochemical aptasensor for Pb2+ was constructed based on the layer-by-layer assembly of graphene (GR) and anthraquinone -2-sulfonic acid sodium salt (AQMS) on the surface of Pb2+ aptamer. The mercapto-modified Pb2+ aptamer was first anchored on a gold electrode. Then the highly conductive material of GR was adsorbed on apt through the unique π-π stacking interaction, which was further used for the assembly and signal amplification of the electroactive AQMS. Upon interaction with Pb2+ ions, the apt on the aptasensor undergone conformational switch from a single-stranded form to the G-quadruplex structure, causing the GR assembled with AQMS releasing from the electrode surface into solution. As a result, the electrochemical signal of AQMS on the aptasensor was substantially reduced. Base on this concept, a useful platform for detection of Pb2+ ions was constructed. Under the optimal experimental conditions, the attenuation of peak currents (△Ipa ) showed linear relationship with the logarithm of Pb2+ concentrations (lgCPb2+) over the range from 5. 0×10-10 to 5. 0×10-8 mol/ L. The detection limit was estimated to be 6. 0×10-11 mol/ L.

Objective To analyze the prevalence of diabetes and its impact on the quality of life (QOL) among Jingpo ethinic residents in Yunnan province.Methods Questionnaire survey and fasting blood glucose (FBG) testing were conducted among 1367 Jingpo residents aged ≥ 35 years selected with random sampling method in Mangshi municipality of Dehong prefecture in Yunnan province.The Medical Outcome Study 36-Item Short-Form Health Survey (SF-36) was used in the survey.Results The prevalence rate of diabetes among the Jingpo residents was 4.1％,and 4.2％ for males,4.0％ for females.Among Jingpo diabetic patients,mean scores for the domains of physical functioning (PF),role physical (RP),bodily pain (BP),general health (GH),vitality (VT),social function (SF),role emotional (RE),mental health (MH),physical component summary (PCS) and mental component summary (MCS) were (84.64 ±16.81),(53.13 ±45.24),(71.70 ± 24.28),(49.46 ± 21.38),(65.09 ± 11.02),(90.08 ± 14.00),(79.17 ± 39.98),(70.29 ± 13.73),(57.12 ± 9.39) and (55.07 ± 6.58),respectively.The identified diabetic patients had significantly lower QOL scores for the doamins of PF,RP,BP and PCS than their counterparts,respectively (P＜0.05).The results of the multiple linear regression analysis showed that older Jingpo residents had lower scores in the domain of PCS and MCS (P＜0.01);men has lower scores in the domain of PCS and MCS than women (P＜0.01);the higher the level of education,the higher the scores of PCS and MCS (P＜0.01);married Jingpo residents had higher scores in domain of PCS than those of unmarried and divorced (P＜0.01);the diabetic patients had lower scores of PCS than their counterparts (P＜0.01).Conclusion It is necessary to strengthen the health education for the elderly and people with low level of education,and improve the management of patients with diabetes,so as to effectively improve the QOL of Jingpo ethnic minority residents.

Objective To provide useful information on reducing risky drinking for the Dept.of Public Health taking a county in Yunnan province as an example to explore the risk factors related to risky drinking.Methods A total of 574 participants identified as Miao,Yi and Han People at or older than 12 years old,who had been living there for 6 months or more were selected and surveyed in 5 townships in the county through stratified sampling.Alcohol consumption was collected using the beverage-specific quantity frequency (BSQF) method and analyzed using binary logistic regression and chi-square test.Results The number of drinkers in the family,undesirable drinking environment among friends and enculturation (β =0.073) could increase the likelihood of risky drinking.Risky drinking pattern was positively associated with age (β =1.006),and negatively associated with gender (β =-2.947) and awareness of risky drinking among rural residents.Conclusion The important measures to control risky drinking behavior in terms of health promotion and education include reducing the number of drinkers in the family,and preventing from undesirable drinking environment among friends and harmful drinking culture.These measures are crucial to prevent early onset of alcohol drinking among teenagers and to reduce risky drinking among middle aged and aged population.
